&DRIFT: TRACK: WEIGHTED-DISTRIBUTION


WEIGHTING-FUNCTION

  The distribution of the points along the track can be
  specified in either of 2 ways:

  - As a function in terms of the variable T that runs from
    0 at the starting point of the track to 1 at the end
    point of the track.
  - As a set of 2 matrices separated by the word 'VS', the
    first matrix is the weight and the second should be a
    vector of coordinates defined like T, i.e. running from
    0 to 1 for begin and end point of the track.

  The function should return only non-negative values with a
  total contents larger than zero. The function need not be
  normalised.
